Type (f in Indian Museum ; 9 in Pusa collection. 



iY.S. — The conspicuous shining black spot on the light grey 

 thorax, and the unusually constructed male genitalia will render 

 this species easily distinguished. 



Geranomyia semifasciata, mihi, sp. nov. 

 9 . Darjiling. Long. 5^ mm. 



Head light grey. Frons very narrow. Proboscis black, as 

 long as head and thorax together. Antennae brownish yellow, 

 flagellum darker than scape. 



Thorax. — Neck yellowish, a dorsal distinct dark brown stripe 

 and a lateral less distinct one on each side. Dorsum of thorax 

 yellowish, with a brownish tinge. Three very narrow ill-defined 

 but obvious reddish brown stripes, well separated; the median one 

 barely reaching the anterior margin. 



Behind the suture the space wholly occupied, except the wide 

 greyish post-sutural depression, by two large brownish spots, the 

 colour gradually merging in that of the sides. 



Sides of dorsum with whitish reflections. Sides of thorax 

 yellow ; scutellum and metanotum brownish. 



Abdomen brownish yehow, posterior border of each segment 

 blackish, the colour extending along the sides more or less, oviposi- 

 tor yellowish. 



Legs pale yellowish, tips of femora a little blackish. 



Wings pale yellowish grey. Auxiliary vein ends midwaj^ 

 between the base of the 2nd vein and the tip of the ist. The 

 2nd begins at the middle of the wing ; the praefurca is nearly as 

 long as the rest of the vein, which is a little sinuous and curved 

 upwards at tip. Marginal cross- vein placed distinctly beycnd the 

 middle of the marginal cell. Base of 3rd vein two and a half times 

 as long as anterior cross-vein. Discal cell much broader distally, 

 a little longer than double its average width, and a little longer than 

 the 2nd and 3rd posterior cells. Posterior cross-vein in a line 

 with the base of the discal cell, the anterior cross- vein is in the 

 same straight line. 



The markings of the wing are brown in colour, and are placed 

 as follows : Three narrow streaks begin (anterior to the middle of 

 the wing) on the costa, and extend posteriorly nearly to the middle 

 of the wing, the first streak nearly basal. A fourth narrow costal 

 streak begins at the tip of the auxiliary vein and extends to the 

 base of the 3rd vein. The next costal streak (the widest of all) is 

 over the marginal cross-vein, and is clear cut, being suddenly re- 

 duced to half its width at the 2nd longitudinal vein, beyond which 

 it is continued, terminating abruptly at the 3rd vein. The two
